EXTENSIONSTEP.

Application filedJanuary .20, 1908. 1S'eria1N o.411,778. v

To a?! zrlmm it may concern:

citizen of the United. States, residing at Binghamton, in the county ofBroome and State of New York, have invented a new and usefulExtension-Step. of which the followin; is a specification.

This invention relates to extension steps for railway coaches and itsobject is to provide a simple and etiicient device of this characterwhich can be readily attached to the ordinary steps of a coach and whichdispenses with the use of the handstep such as ordinarily employed.

Another object is to provide a step particularly designed for use inconnection with vestibule coaches, the same being so positioned thatwhen it is folded or raised into inoperative position it will house thefixed ,steps of the car and thus prevent persons from boarding the coachafter the vestibule has been closed.

A further object is to provide simple means for locking the step inraised position, said means being also utilized for operating the step.

Afurther object is to provide an extension step which, when in closed orinoperative position, :wrves to shield the steps and keep them cleanwhile the coach is in motion.

'ith these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying. drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a perspective view of a portion of a coachand showing the step applied thereto. Fig. 2 is a vertical sectionthrough the step and the parts to which it is connected, said step beingshown in closed position. Fig. 3 is a front elcvation of one end portionof the step and the adjoining parts, saidzstep being lowered asindicated in Fig. 1. l

Referring to the figures by characters of "reference, A designates acoachzrom the vestibule B of which extends steps C of the usualconstruction, the door-Z13 of; the vestibule being designed to closeabcvelthe steps as ordiiiarilv while a movable floor section B isdesigned to be placed withinfthe vestibule and almve the steps asordinarily. The present invention consists of "an extension step 1having side supports or hangers 2 and Specification of Letters Patent. i

l 3 which a re Patented Sept.

I11 order that the extension step may be conveniently operated a lever 5is mounted upon the inner face of one side of the steps C and providedat one end with a crank extension 6 while i ts other end is secured to apivot 7 extending through the side of the steps and secured to an arm 8.This arm is in turn pivoted to one end portion to the link 9 as shown at10 and this link is pivotally connected to the side 2 of step 1 asindicated at 11. The distance between the pivots 10 and 11 is the sameas the distance between the pivots 7 and 10' and the combined length ofthe arm 8 and link 9 is such that the ste 1 when lowered will be heldparallel with the ste )S C as shown in Figs. 1 and 3. A counter )alance12 extends from the side 3 of step 1 and may be of any suitable size andproportions, this counterimlance being designed to assume a positionclose to one side of the steps C when the extension step is lowered.henever it is desired to raise the step 1' so that the step C will becompletely housed the operator pulls upward on the crank 6 and lever 5so as to swing the arm 8 upwardly.

This will pull on link 9 and step 1 will be caused to swing on itspivots 4. \Yhcn said step assumes an upright position as shown in Fig. 1the pivot 10 will be. brou ht into position in alinement with pivot 4,the link 9, arm 8 and lever 5 thus belng brought parallel.

p preferably suitably ornament-e Be it known that'l. lRAXK i\. '1 Use, al and lap the sides of the lower step C and are 1y connected theretoadjacentthe Lever 5 can then be swung downward against the adjoiningstep 5 and past the dead center as shown in Fig. 2 thus forming agravity lock so that the step 1 will be securely locked in closedposition and can not be lowered unless the lever 5 is first raised pastthe dead center and swung downward. Obviously when the extension plateis closed it becomes impossible for any pelsons to board the car andmoreover said step will act as a shield to prevent cinders, etc. fromaccumulating upon the. steps C.

What Is claimed 15:

1. The combination with a car vestibule steps.

the extension step into position in front of including a door, a panel,and steps below the I door and panel; of an extension step pivotl allyconnected to the car steps, means operated independently of the panelfor shifting the car steps and in alineinent with the door 2 ofthe'vestihule, said extension step when folded constituting a cover forall of the car i 2. The combination with a car vestibule includingadoor, a panel, and steps below the ated independently of the panel forshifting door and panel; of an extension step pivotally connected to thecar steps, means oper the extension step into position in front of thecar steps and in alineinent with the door of the vestibule, saidextension step when folded constituting a cover for all of the car isteps, and means below thevestibule panel disposed to be concealedbetween saii raised, said means including an actuating lever having afixed pivotal point.

4. The combination with car steps; of an extension step pivotallyconnected thereto and constituting a housing therefor, an actuatinglever mounted above the car ste )s and l'steps and the folded extensionstep, and link connections between said lever and the extensioii step,said lever and links being movable in parallel planes and. arranged toconstitute agravity lock when shifted to a predetermined lposition. 5.T10 combination with car steps; of a i countei'lialaiiced extension steppivotal'ly I connected thereto, a pivot arin connected to the car steps,a link connection between the arm and extension step, and means foractuating the arm to fold the link thereon and raise and lock theextension step, said means having a fixed pivotal'point.

In testimony that I claim the foregoing as my own, Iv have heretoallixed my signature in the presence of two witnesses.
